I will say a few things in favor of discord despite my vote for teamspeak: Discord would be a better fit for a growing community of all kinds of people. Discord is more like a chat room with many sub channels of different purposes, and voice is not the main purpose of the application. That can be more appealing to those who do not have a proper microphone setup or just choose not to use it. Discord could also be used for announcements on events, starting groups for games, general discussion, and more. Take a look at how Your Overwatch has their channels set up:

@JustARunaway I agree with you. I use discord when im looking for HotS tournaments or just to see whats going on in the competitive scene. I vote that we do both and if you need any help with content creation or anything let me know!

I only really like Discord just because of the in-game overlay it has for voice chat. I feel it wouldn't make a lot of sense to have it if we have the website. (Unless it's the goal to get rid of it.) I feel it would be nice for mobile users who want to check

I'm really 50/50 about both of them. I still like Teamspeak just because I'm so used to it. I'm happy to use whatever Crit Cola decides to roll with.
